The impact of mindfulness therapy combined with mentalization-based family therapy on suicidal ideation in adolescents with depressive disorder: randomized intervention study.

BACKGROUND: Adolescents with depression who engage in non-suicidal self harming behaviors are more likely to adopt negative coping strategies when faced with negative events. Therefore, these patients should be introduced to positive coping strategies. Evidences have showed that mindfulness-based interventions can positively impact the psychology of patients with mental disorders. This study was to explore the impact of a combination of mindfulness therapy and mentalization-based family therapy (MBFT) on suicidal ideation in adolescents with depressive disorder. METHODS: Eighty adolescent patients with depression and suicidal ideation admitted to our hospital from September 2021 to February 2022 were selected as subjects. They were divided into a control group and a study group using the random number table method, with each group comprising 40 subjects. The control group received MBFT, whereas the study group received both mindfulness therapy and MBFT. The psychological status and suicidal ideations of the two groups were compared before and after the intervention. RESULTS: The psychological health scores of both groups of patients were lower after the intervention, with the scores of the study group being lower than those of the control group (P < 0.05). The scores on the suicidal ideation scales for both groups were lower after intervention, and the study group scored lower than the control group (P < 0.05). The absolute values of the differences in psychological health scale scores and suicidal ideation scale scores before and after the intervention were higher in the study group than in the control group (P < 0.05). CONCLUSION: The combination of mindfulness therapy and MBFT can improve the psychological condition of adolescents with depression, reduce their suicidal ideations, and help them develop a healthy and positive outlook toward life, making this method worthy of clinical recommendation.

Silencing of TRAF5 enhances necroptosis in hepatocellular carcinoma by inhibiting LTBR-mediated NF-κB signaling.

Background: Hepatocellular carcinoma (HCC) is a common malignancy with poor prognosis and high mortality. This study aimed to explore the oncogenic mechanisms of TRAF5 in HCC and provide a novel therapeutic strategy for HCC. Methods: Human HCC cell lines (HepG2, HuH7, SMMC-LM3, and Hep3B), normal adult liver epithelial cells (THLE-2), and human embryonic kidney cells (HEK293T) were utilized. Cell transfection was performed for functional investigation. qRT-PCR and western blotting were used to detect mRNA expression of TRAF5, LTBR, and NF-κB and protein expression of TRAF5, p-RIP1(S166)/RIP1, p-MLKL(S345)/MLKL, LTBR, and p-NF-κB/NF-κB. Cell viability, proliferation, migration, and invasion were evaluated using CCK-8, colony formation, wound healing, and Transwell assays. Cell survival, necrosis, and apoptosis were assessed using flow cytometry and Hoechst 33342/PI double staining. Co-immunoprecipitation and immunofluorescence were performed to determine the interaction between TRAF5 and LTBR. A xenograft model was established to validate the role of TRAF5 in HCC. Results: TRAF5 knockdown inhibited HCC cell viability, colony formation, migration, invasion, and survival but enhanced necroptosis. Additionally, TRAF5 is correlated with LTBR and TRAF5 silencing down-regulated LTBR in HCC cells. LTBR knockdown inhibited HCC cell viability, while LTBR overexpression eliminated the effects of TRAF5 deficiency on inhibiting HCC cell proliferation, migration, invasion, and survival. LTBR overexpression abolished the promotive function of TRAF5 knockdown on cell necroptosis. LTBR overexpression undid the suppressive effect of TRAF5 knockdown on NF-κB signaling in HCC cells. Moreover, TRAF5 knockdown suppressed xenograft tumor growth, inhibited cell proliferation, and promoted tumor cell apoptosis. Conclusions: TRAF5 deficiency facilitates necroptosis in HCC by suppressing LTBR-mediated NF-κB signaling.

Evaluation of the effect of a resorbable membrane on the closure of palatal fistulas.

Purpose: A palatal fistula following the closure of palatal clefts remains a difficult clinical complication. Surgical treatment of fistulas is often complicated, with high recurrence rates. We present our results of fistula closure augmented with GTR, a resorbable membrane designed to promote guided tissue regeneration. Methods: We reviewed the records of 75 patients operated on between 2008 and 2022 for closure of the palatal fistula. The patients included 24 who underwent fistula closure augmented with GTR and 51 who underwent fistula closure with other techniques. We reviewed the age at surgery, sex, fistula location, and outcome. Operation success was defined as an asymptomatic patient with a healed fistula on clinical examination. Results: The overall fistula closure rate was 79.1% in the GTR group and 76.5% in the non-GTR group(p = 0.79). Discussion: The success rate of fistula closure in the GTR group is comparable to that in the non-GTR group in this study. An additional advantage is that this procedure does not require harvesting any autologous tissue and reduces tissue damage in the long term.

Comparison of velopharyngeal morphology of two palatoplasty techniques in patients with hard and soft cleft palate.

Purpose: The study aims to compare the velopharyngeal morphology of hard and soft cleft palate (HSCP) patients after Furlow and Sommerlad palatoplasty. Patients and methods: A total of 51 patients (20 cases in Furlow palatoplasty group, 16 cases in Sommerlad palatoplasty group and 15 normal children in the control group) were included in our study. Velopharyngeal function and speech outcomes of patients with HSCP who had either Furlow palatoplasty or Sommerlad palatoplasty for cleft palate repair were evaluated by perceptual speech assessment (PSA), lateral cephalometric radiographs and nasopharyngoscopy. To assess velopharyngeal morphology of patients treated with two techqiques, we analyzed measurements such as velar length, pharyngeal depth, and the Adequate ratio (the ratio of velar length to pharyngeal depth). Furthermore, skeletal landmarks including cranial base, cervical vertebrae, posterior nasal spine which were defined as the pharyngeal triangle were measured. Finally, the position of the point U relative to the pharyngeal triangle were compared. Results: Velopharyngeal closure (VPC) rate in Furlow palatoplasty group accounted for 90%, while that in Sommerlad palatoplasty group was 81.3%. PSA of the former group was significantly better than that of the latter group (P < 0.05). Velar length, pharyngeal depth and the Adequate ratio (1.37 ± 0.14 vs. 1.41 ± 0.15) were comparable between the Furlow group and control group (P > 0.05), while Sommerlad group had a shorter velar length, deeper pharyngeal depth and a smaller Adequate ratio (1.20 ± 0.18) compared to the above two groups (P < 0.05). Furhermore, the point U of Sommerlad group in the pharyngeal triangle was higher than that of the other two groups. Conclusions: In the treatment modality of patients with HSCP, both Furlow palatoplasty and Sommerlad palatoplasty seem to be effective. Furlow palatoplasty appears to have velopharyngeal morphology similar to normal control group., while Sommerlad group shows a shorter velar length, deeper pharyngeal depth and a smaller Adequate ratio.

[Mechanism of Huangqi Guizhi Wuwu Decoction in treatment of rheumatoid arthritis based on UPLC-LTQ-Orbitrap-MS, network pharmacology, and cell experiment].

In this study, ultra-high performance liquid chromatography-linear ion trap/electrostatic field orbit trap combined-type mass spectrometry(UPLC-LTQ-Orbitrap-MS) was used to analyze the main active components of Huangqi Guizhi Wuwu Decoction(HQGZ). A total of 50 active components were identified from HQGZ and 108 potential targets of the components related to the treatment of rheumatoid arthritis were retrieved based on network pharmacology, including 87 key targets, followed by Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment of the targets. The result indicated that HQGZ may exert therapeutic effects mainly through the sphingolipid signaling pathway, tumor necrosis factor(TNF) signaling pathway, as well as the positive regulation of ribonucleic acid(RNA) polymerase Ⅱ promoter transcription, inflammatory response and other biological processes. At the same time, cell experiment was performed to verify the key proteins in the TNF signaling pathway. The results demonstrated that HQGZ significantly reduced the expression of caspase-3(CASP3), TNF, relaxed(RELA) protein, and IkappaB kinase beta(IKBKB) in fibroblast-like synoviocytes induced by TNF-α. The results of UPLC-LTQ-Orbitrap-MS, network pharmacology and cell experiment showed that the active components in HQGZ may inhibit inflammatory response and regulate immune function and cell apoptosis by modulating key proteins in TNF signaling pathway to treat rheumatoid arthritis.

Mechanisms of inhibiting human leukemia cell lines by serum of rats treated with compound banmao capsule.

Compound banmao capsule (CBC) is a traditional Chinese medicinal formula composed of extracts from 11 organisms. The present study investigated the mechanism of CBC on the biological behavior of human leukemia cell lines using seropharmacological methods. CBC-containing rat serum was prepared by intragastrical administration of CBC to rats. The proliferation of human leukemia HL60 and K562 cell lines was assayed by measuring cell viability with the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium method, while cell cycle distribution and the rate of apoptosis were evaluated with flow cytometry. The mRNA expression of vascular endothelial growth factor A (VEGF-A) and chemotactic and inflammatory genes in human leukemia cell lines was examined using reverse transcription quantitative-polymerase chain reaction methods. It was revealed that the proliferation of K562 and HL60 cells was significantly inhibited by the CBC-containing rat serum at 72 h. The CBC-containing serum also promoted the apoptosis of K562 and HL60 cell lines. The CBC-containing serum altered the cell cycle progression of K562 and HL60, increasing the proportion of the cells in G1 phase and decreasing the proportion of the cells in S phase. Attenuated expression of VEGF-A and a decreasing trend in the expression of chemotactic and inflammatory genes were identified following treatment with CBC-containing serum in HL60 and K562 cells. In conclusion, CBC-containing serum exerted an inhibitory effect on the growth of K562 and HL60 cells by decreasing cellular proliferation, promoting apoptosis and cell cycle arrest, and decreasing the expression of VEGF-A, and chemotactic and inflammatory genes.

Application of Somatic Embryogenesis in Woody Plants.

Somatic embryogenesis is a developmental process where a plant somatic cell can dedifferentiate to a totipotent embryonic stem cell that has the ability to give rise to an embryo under appropriate conditions. This new embryo can further develop into a whole plant. In woody plants, somatic embryogenesis plays a critical role in clonal propagation and is a powerful tool for synthetic seed production, germplasm conservation, and cryopreservation. A key step in somatic embryogenesis is the transition of cell fate from a somatic cell to embryo cell. Although somatic embryogenesis has already been widely used in a number of woody species, propagating adult woody plants remains difficult. In this review, we focus on molecular mechanisms of somatic embryogenesis and its practical applications in economic woody plants. Furthermore, we propose a strategy to improve the process of somatic embryogenesis using molecular means.

Graphene-supported CoPc/TiO2synthesized by sol-gel-hydrothermal method with enhanced photocatalytic activity for degradation of the typical gas of landfill exhaust.

This work was focused on the enhanced photocatalytic activity of cobalt phthalocyanine (CoPc)/TiO2under visible light irradiation supported on reduced graphene oxide (RGO). A series of RGO/CoPc/TiO2nanocomposites were synthesized via sol-gel-hydrothermal method. The photocatalysts were characterized by X-ray diffraction, BET surface area, Scanning electron microscopy, Raman spectra, Fourier transform infrared spectra, UV-Vis spectra and Photoluminescence spectra. The results demonstrated that the TiO2existed as anatase phase both of CoPc/TiO2and RGO/CoPc/TiO2composites, and the absorption range in visible light of RGO/CoPc/TiO2composites were broadened further. The photodegradation results of diethyl sulfide, the typical gas of landfill exhaust, under visible light revealed that RGO/CoPc/TiO2nanocomposites exhibited much higher photocatalytic activity than CoPc/TiO2and pure TiO2, indicating the ideal amount of RGO was 7.5 wt.%, the optimal amount of 7.5% RGO/CoPc/TiO2composite on each plat was 0.3g and the degradation efficiency of diethyl sulfide was about 90%.

[Study on the distribution and characteristics of Chinese medicine syndrome in patients with nonalcoholic fatty liver disease].

OBJECTIVE: To supply evidence for establishing the standard for Chinese medicine (CM) syndrome differentiation by investigating the distribution and characteristics of CM syndromes in patients with nonalcoholic fatty liver disease (NAFLD). METHODS: 928 NAFLD patients' symptoms, signs, tongue and pulse parameters were studied by clinical epidemiologic survey. And the results were analyzed by the cluster analysis and factor analysis. RESULTS: The results of cluster analysis showed that the CM syndrome typings of fatty liver patients were mainly classified as dampness heat accumulation, Pi deficiency with dampness phlegm, Gan-qi stagnation and Pi deficiency, phlegm stasis accumulation, and Gan-Shen insufficiency, which were in accordance with clinical practice. The results of factor analysis indicated that overweight/obesity, abdominal distension, hypochondriac pain, discomfort in the hepatic region were common "condition factors" of fatty liver patients. The 5 "syndrome factors" such as dampness heat accumulation, Pi deficiency with dampness phlegm, Gan-qi stagnation and Pi deficiency, phlegm stasis accumulation, and Gan-Shen insufficiency showed identification significance in syndrome typing. CONCLUSIONS: The basic CM syndrome typings of NAFLD were dampness heat accumulation, Pi deficiency with dampness phlegm, Gan-qi stagnation and Pi deficiency, phlegm stasis accumulation, and Gan-Shen insufficiency. The four parameters of fatty liver patients could be classified by statistical analysis as condition factors and syndrome factors (which could reflect CM syndrome characteristics), which could provide certain evidence for establishing CM syndrome differentiation standards.

The state of insulin resistance in patients with nonalcoholic fatty liver and the intervention with Gankangyin.

OBJECTIVE: To explore the correlation of nonalcoholic fatty liver (NAFL) with insulin resistance and the intervention of it by Gankangyin(GKY). METHODS: Ninety-six patients with NAFL were randomly assigned into the treated group and the control group. They were treated with GKY and Silymarin for 3 months respectively. Oral glucose tolerance test (OGTT) and insulin release test (IRT) were conducted and insulin sensitivity indexes were determined before and after treatment. And 32 healthy nonalcoholic persons were enrolled and used as the healthy control group. RESULTS: Before treatment, the levels of blood glucose and insulin at different time points in OGTT test, and the insulin resistance index (IRI) were significantly higher (P < 0.05 or P < 0.01) while insulin sensitivity index (ISI) and insulin active index (IAI) were lower (P < 0.05 or P < 0.01) in the NAFL patients than those in the healthy persons. After treatment, the above-mentioned raised criteria were significantly lowered (P < 0.05, P < 0.01) and the lowered criteria were significantly increased (P < 0.01) in the treated group, while in the control group all the criteria were insignificantly changed (P > 0.05). CONCLUSION: Evident insulin resistance exists in NAFL patients. GKY could increase the insulin sensitivity, thus improving the state of insulin resistance in NAFL patients.

[Relationship between phlegm-stasis syndrome and fibrinolytic status in patients with non-alcoholic fatty liver].

OBJECTIVE: To explore the relationship between phlegm-stasis syndrome (PSS) and the fibrinolytic status in patients with non-alcoholic fatty liver (NAFL). METHODS: Seventy patients with NAFL were divided into the PSS group and non-PSS group according to TCM Syndrome typing, and a control group consisted of 28 healthy subjects was set up. Levels of plasminogen (PLG), tissue plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1) and D-dimer were determined and compared. RESULTS: The activity of t-PA in NAFL patients was significantly lower than that in the control group (P<0.05), and PLG and PAI-1 were significantly higher than those in the control group (P<0.05). In respect to the TCM Syndrome typing, in patients of PSS, t-PA was significantly lower and PLG, PAI-1 were significantly higher than those in patients of non-PSS (P<0.05 or P<0.01), while D-dimer was insignificantly different between patients of the two Syndrome types (P>0.05). CONCLUSION: NAFL patients of PSS type shows significant lower of fibrinolytic activity, indicating that there is certain degree of microcirculatory disturbance and hyper viscosity state, so the application of dissolving phlegm and dispelling stasis principle in treating NAFL is significant.

[Liver fibrosis indexes in nonalcoholic fatty liver disease].

OBJECTIVE: To assess the clinical utility of liver fibrosis indexes determination in patients with nonalcoholic fatty liver disease. METHODS: Liver fibrosis indexes of 79 patients with fatty liver, diagnosed by B ultrasonic echography, 37 patients with posthepatitic cirrhosis patients and 32 healthy subjects were determined. RESULTS: The level of procollagen III(PC III), hyaluronic acid (HA), collagen IV(C IV), laminin (LN) in the fatty liver cases were significantly higher than those of healthy subjects (P<0.05 - 0.01), but lower than those in the liver cirrhosis cases (P<0.01). The difference of PC III, C IV, LN between the severe and early fatty liver cases was significant (P<0.05 - 0.01). Positive rate of these indexes was higher in severe cases. CONCLUSION: There is a trend of liver fibrosis in severe fatty liver patients. Combined determination of liver fibrosis indexes may help the diagnosis of liver fibrosis in the fatty liver patients.
